CON TAINING-CAN To all whom it mag concern:

Be it known that I, CLARENCE M. SrMonns, citizen of the United States,residing at San Anselmo, in the county of Marin and State of California,have invented new and useful Improvements in Containing-Cans, of whichthe following is a specificationv My invention relates to improvementsin containing cans and especially that class which is designed tocontain hermetically sealed goods of any description, and which areknown as sanitary cans; such cans being sealed without the use ofsolder, or other substance which may have deleterious effect upon thecontained fruit. 7

It consists in a means for closing and hermetically sea ling the can aftr the contents of the can have been proper y put or processed, and inreadiness for the sealing.

Referring to the accompanying drawings for a more complete explanationof my invent-ion,I igm'e 1 is a side elevation,

partly in section, of the can and top before assembling. Fig. 2 is anenlarged section of the seamed top and can.

The ordinary method for preparing hermetically sealed goods for themarket is to fill the cans, pass them through what is known as theexhaust box, in which they are heated so as to, drive out any air thatmay hccontained in the cans, then place the tops on the cans and passthem through the.

closing machine. In thus passing the open can through the exhaust box,the contents swell more or less by reason of the heat, and project abovethe top of the can, so that this projecting portion being above thesurface of the liquid with which the can is filled, becomes scalded,which is a serious objection, especially in high grade fruit, and in theforcing of the top or cover on in the closing machine, the fruit is moreor less crushed and bruised, and portions get between the flange of thecan and the cover, and prevent a perfectly air-1 ight joint being made.

In this invention the cans and covers are made with a. peculiarinterlocking flange so that the cover may be snapped on over the flangeof the can body, after the can has been filled, and before it goes intothe exhaust box, and the cover, while being prevented from coming ml,h-xlvcs space mmllgh to allow the proper exhaust. or discharge of vapor.and at lhesumc time pron-ms the )l'hlfitfitl, am; from gelling betweenlllt' liaugc ol the can Speeifleativn oil-letters Patent- Patented Sept.14, 1909.

I and the body. It also avoids the handling l of the cans while they arehot.

I The cans which are formed in large quantities in the can factories andare shipped to various points where they are to be used, ordiuarilv havea substantially radially projecting fiange with which the cover, also zproperly flanged, will be double-seamed as it is called, when the two-are put together. These projecting edges of the can are easily damagedin the process of shipment and handling, and when so damaged, there'i'sgreat loss, because the heads will not close properly with them. i

In my invention, the upper edge of the can A is turned over to form arim. 2, the outer edge of whichis turned downwardly, as shown, and thisdown-turned edge forms a resistant shapewhich will prevent its beingdamaged by rough usage.

The cover 3 is formed with an arched, an. uular rim 4 which is turneddownwardly, thence bent inwardly and upwardly as shown at 5. Thisinturned edge 5 is of such diameter that the cover can, by a littlepressure, be caused to snap over the outwardly turned edge 2 of the canbody, and thus engaged,,it will not be possible to again remo e thecover,'but the engagement is a looseone which allows any steam or vaporfrom the contents of the can to escape when the can is placed-in theexhaust box after being filled. The contents of the can are alsoprevented from swelling and risin above the scalding is revented. Thecontents are also prevented rom extending over the edges of the can asthe cover is already in lace, and after the filling'and exhausting avebeen completed, the seam is formed by dies which are not here described,instead of usingrollersby which the usual doublescam's of ordinarv cansare formed. The closiine may thus be completed without. any handling ofthe cans whilehot, as they can be delivered automatically and directlyfrom the exhaustlmx to the closing dies. and all the objectionablel'cnlurvs heretofore lu'cutiomul, are llvuhhul,

The invention may be applied to oval. quare. or irregular mum u well asto round nuns,
